What is the parameter in y-axis
hardenability
hardness
temperature
cooling rate
Generaly hardenability of steel can be
increased by adding alloying elements
decreased by adding alloying elements
does not change by adding alloying elements
none of these
Hardenability can be increased by shifting transformation curve to the ................. in the TTT diagram
right
left
top
bottom
Quenching is
fast cooling process
slow cooling process
moderate cooling process
Hardness at the quench end is
maximum
minimum
in between maximum & minimum
unpredictable
In the experimental setup described water jet is created by
level difference of water in the tank
pump
Furnace temperature(in degree centigrade) was set at around
1200
1050
950
850
Cylindrical msample was fixed in the quench setup in
vertical position
horizontal position
inclined position
To get the hardenability curve which setup(s) is/are required
Furnace
Quench setup
hardness tester
Microscope
Which one more hardenable material?
EN24
EN8
Which cooling curve will make the sample harder?
red
blue
This picture showing
temperature setup in furnace
Jominy end quench setup
hardness minor load set
hardmess major load set
which hardness test was done on the cooled sample?
Vicker hardness test
Rockwell C scale
Rockwell B scale
Brinell Hardness Test
What operation is going on?
Muffle furnace temperature setting
Temperature fine control
opening the door lock of the furnace
power on of the furnace
What was the function of the pump in the quench setup?
creating water jet
filling up the high level reservoir from collector tank at the bottom
drain the water
There is no pump in the system
Quenching of steel produce
austenite
pearlite
bainite
martensite
Furnace heating of the sample produce
austenite
pearlite
bainite
martensite
